Seagate 1200 SSD 400GB SAS Enterprise Drive

The Seagate 1200 SSD ST400FM0053 is a 2.5-inch enterprise solid-state drive with a 400GB capacity. It connects via a SAS 12Gb/s interface and uses MLC memory components. The drive is designed for consistent performance in demanding server environments.

Suits write-intensive server workloads.

This SSD targets enterprise applications that require ultra-fast, consistent performance and redundant failover I/O paths. It helps remove storage bottlenecks under complex, write-intensive workloads. Buyers building standard desktop PCs or consumer laptops should look elsewhere, as the SAS interface requires a compatible server backplane or controller.

SAS 12Gb/s interface dictates compatibility

The single specification that decides fit is the SAS 12Gb/s interface, which requires a matching controller or backplane supporting that protocol. Random read performance reaches up to 110,000 IOPS and random write up to 40,000 IOPS at 4KB. Power draw is 2.72W idle and 3.71W active within an operating range of 0°C to 60°C.

Questions about this item

Does this ST400FM0053 require a SAS 12Gb/s controller to operate?

Yes, the drive uses a SAS 12Gb/s interface and needs a compatible SAS controller or HBA in the host system to function.

Can the 2.5 inch ST400FM0053 share a SAS backplane with older 6Gb/s drives?

The drive supports SAS 12Gb/s and will negotiate down to 6Gb/s on a shared backplane, allowing mixed-speed operation.

How do I confirm the 400GB ST400FM0053 is delivering its rated 110,000 read IOPS after installation?

Run a 4KB random read benchmark such as fio or Iometer at queue depth 32 and verify sustained IOPS near 110,000.
